Java Enterprise

Pragmatic Programmer Stuart Holloway said in a tweet recently, “Anybody can be agile in a green field. Show me your 3rd, 4th, and 5th releases.” Well, we've been maintaining Oracle Mojarra JSF for 32 releases and, we’ve found hudson a completely invaluable tool for maintaining agility as the technology matures and requires maintenance across all the versions we've ever released...

I'm trying to get the first snapshot of JSF 2.2 published and I've just scanned through the svn logs and arrived at the following text, from which I'll derive the "Changes between 2.1 and 2.2" content. * Deprecate the CURRENT_COMPONENT and CURRENT_COMPOSITE_COMPONENT attributes* Fix incorrect VDLDoc

Next week I will be presenting a free webinar about Java EE 6 and Glassfish 3.1. The title can be translated to English as: "Java EE 6 and Glassfish 3.1: Simplicity + Ligthness = Productivity". The reason the title is in Portuguese is because this will be a webinar targeted at Brazilian Java EE and Glassfish users - as far as I know it will be the first webinar in Portuguese on these...

It's hard to know the exact numbers, but I'll venture a guess that well over half of the JSF sites that exist in the world are running Oracle's Mojarra implementation of the JSF spec. Did you know that this implemention is the first large part of JavaEE (then J2EE) to be open-sourced, way back in 2004? As with any decent open source project, we have public continuous integration, a public...

Back from office, read some news updates on Aquarium, remembering when I was in High School, I used to do programming in Pascal Programming Language. Simple application for PC run on x86 machine is just a single file or a bit of files only, do all process needed; such as computing, data or I/0 access and network interfacing. In todays Distributed Computing model, application is not just a single...

About three weeks ago, I called for the community to submit entries for a contest to design a logo for the JSF specification. Sixteen different individuals submitted 32 entries. Thank you very much for contributing! Per the recommendation of Arun Gupta and Imre Oßwald, I used a web voting platform to determine the winner, and here it is. I would have uploaded it to the Official Homepage...

About two weeks ago, I called for the community to submit entries for a contest to design a logo for the JSF specification. Sixteen different individuals submitted 32 entries. Thank you very much for contributing! I happen to believe that Instant Runoff Voting (or a similar method) is the last best hope to save representative democracy in America, so I decided to use a very nice and simple web-...

The analysis of the recent Amazon EBS outage has been posted on the AWS blog [1]. I read it and was incredibly impressed with the detail, depth, clarity and competency shown. Of course, they need to impress the users with those things because they're asking us to trust them with our crown jewels. Even knowing that they are in the business of instilling confidence, it's clear the AWS team has...

So as not to leave this blog dangling, I thought I'd post a notice here too besides the now customary tweet. I have decided to pursue another opportunity, so today is my last day at Oracle. As a bit of history, I joined JavaSoft back in 1997 to work on the first version of EJB and what later became J2EE / Java EE. It's been a long ride and I'm very happy with all that we accomplished (five...

Two Thursdays ago, I called for the community to vote for their top five issues, you responded with 186 votes, the results of which are captured in JIRA filter JSF_2_2_VOTED_ISSUES and in the following chart. You can see that JSF+CDI and multi-component validtion are the two big winners, followed by resource handler improvements and a feature that seems like taking the composite components to...

No, I'm not talking about implementing a Logo JSF RenderKit. I'm talking about a little image that can be used to represent the JSF specification on slides, web-sites, T-Shirts and such. JSF has been around for ten years now and still doesn't have a logo. As Dan Allen has repeatedly said, it's past time for that to change. This blog entry announces a contest to make a logo for JSF. The winner...

Yesterday I facilitated the JSF 2.2 BOF at the CON_FESS 2011 conference. After years of having, but not using my slideshare account, I decided to upload the slides there, at <>. The slides set expectations for JSF 2.2 and give pointers for how to get involved at various levels of interest. After the meeting we held the kick off meeting for the...

If you would like to contribute to the development of the next version of the servlet specification, please nominate yourself and, if possible, please explain how you plan to contribute to the specification. If you would like to track the progress of the spec...

As mentioned earlier and elsewhere, JSF 2.2 is getting started right now. This blog entry is a call for serious, committed participation in the JCP Expert Group dedicated to delivering that specification. Ever since Oracle acquired Sun Microsystems and Java, there has been criticism of their handling of community and JCP. Some have gone so far as to say that Java is no longer free as in speech...

The JSF 2.2 ballot was approved, so now it is time to start speaking up about what you think needs to be in JSF 2.2. Obviously it takes a bit of time to start organizing the Expert Group. But nowadays individuals can join too. So there really is no excuse to start contributing. If you do not know how to get started feel free to comment!

The JavaEE 7 umbrella JSR has been approved. A step in the right direction. Now we'll just have to see what is going to be included for real :)

Java Web Services and XML

For the purpose of creating a nice API for my new project Caligo (more on this in a future blog post), I was looking for a simple solution to access REST web service in Scala. My requirement was simple: access an HTTP web service, and exchange data with him using the JSON format. You can read the full story here and get the gist of the basic implementation:
